If I put a pebble in a jar every time I empty or stack the dishwasher and took one out every time DH does likewise, I would have a very full jar very quickly. If I had a pebble every time I ring my old (now widowed) schoolfriend in Scotland (when we usually chat for over an hour) and took one away every time she rang me....well, what do you think? If I had pebble every time DH takes the recycling all the way out to the bags/boxes in the garage as opposed to leaving them in the utility room pointing hopefully garagewards..........etc etc etc.
Do you have "pebbles" in your life?
Robot mowers. Does anyone have one?
